2 Claims. 1

The invention relates to an electric lamp, and more especially to acombination switch and light control for floor lamps.

The primary object of the invention is the provision of a control ofthis character, wherein it is only necessary to turn the shade of thelamp of the electric lamp for turning on or off the same, therebyeliminating the necessity of looking or feeling for the usual lampswitch, particularly when in the dark, the intensity of the light beingreadily controlled simultaneously when turning on the light.

Another object of the invention is the provision of a control of thischaracter, wherein the same is unique and compact, and avoids the use ofa button or snap-lever switch for service in turning on or off thelight.

A further object of the invention is the provision of a control of thischaracter, which is simple in its construction, thoroughly reliable andeflicient in operation, neat in appearance, thus will not detract fromthe pleasing appearance of the lamp when a part thereof strong, durable,possessing few parts, susceptible of being easily repaired should thecontrol get out of order, and inexpensive to manufacture and install.

With these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter described in detail, illustrated in the accompanyingdrawing, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation partly in section of an electric lamp with thecontrol constructed in accordance with the invention applied.

Figure 2 is a top plan view thereof.

Figure 3 is a horizontal sectional view through the rheostat of thecontrol.

Figure 4 is an enlarged vertical sectional view through the control.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail A designates generally the lampstandard of the electric floor type, and B the shade therefor.

The standard A at its upper end is formed with a cylindrical shapedhollow head In in the form of a crown and this head is fitted with bulbsockets ll, while the removable cover l2 for the said head is providedwith a central opening [2 to receive the fiat insulating disc 24 whichis provided with an upstanding journal stud l3 for the turning axis fora hub I 4 of a lamp shade frame l5 of the shade B, the hub I 4 beingfixed to the arms l6 of the said frame 15. The hub I4 is retained on thestud l3 by a screw l1 and washer l8, respectively.

Stationarily mounted within the head I0 is an insulating base IQ for theresistance coil 20 with which contact is made by a flat rotatablecontact 2| engaged on a pivot 22 centrally fitted at 23 to the base IS,the pivot 22 being threadedly received in the sleeve or hub 24' of thedisc 24 in the cover l2, the disc 24 being of a smaller diameter thanthe central opening 12' forms an annular space 25 for accommodating theinsulated L-shaped member 26 attached to contact 2|. The member 26travels in the annular space 25 and its forked upper end saddles an arml6 of the frame [5 of the shade B, so that when the latter is turnedclockwise or counter clockwise the contact 2l which has one end thereofengaging the resistance coil 20 will be similarly moved.

The coil 20 and the contact 2| are terminally connected electrically ina current supply circuit 21 of a house wiring line (not shown) whichdelivers current to the bulb sockets l I for illumination of the lampbulbs 28 as usual, the coil and contact, 20 and 2| intercept the circuitto the sockets II, for the turning on and off of the bulbs 28. The baseI9 is provided with stops 29 and 30, respectively, and when the contact2! engages the stop 29 the circuit 21 is open, yet when the said contact2! engages the stop 30 the circuit remains closed, the latter beingconstantly closed while the contact 2| traverses the coil 20, andaccording to the position of such contact 2| thereon the intensity ofthe light is increased or decreased. When the contact 2| is movedcounter clockwise the same engages the stop 29 and on moving the contact2| clockwise the stop 30 is engaged thereby.

The shade B completes the movement of the contact 2! and it should beobvious from the foregoing taken in connection with the drawing that thebulbs 28 are lighted and extinguished by turning the said shade B, andalso the intensity of the light is regulated thereby.

What is claimed is:

1. In an electric lamp including a pedestal, an enlarged upper end onsaid pedestal, a lamp shade having a rotating frame on said pedestal, aresistance coil mounted on a circular insulating base secured to occupya stationary position in the enlarged upper end of the pedestal of thelamp, a contact rotatably mounted in the upper 3 end of the pedestalcontacting said resistance and adapted for operation through the mediumof the frame of the lamp shade, a source of current connected to saidresistance, a lamp bulb connected to said contact, and an L-shapedinsulated member secured to said contact having the upper end thereofforked to provide an operboth directions.
